Just to add to the above. If you are going to cover your veggie patch, please make very sure that it isn’t covered with anything the hogs can get trapped in. They can easily become tangled in netting, but can also sometimes put their head and front of spines through things and then not be able to reverse back out again and so becoming trapped.
I have found that putting sticks into the ground fairly close together on exposed soil helps to deter cats from freshly dug soil. Old stalks from herbaceous perrenials can be used for this. The hogs can more easily pick their way between and maybe that sort of area isn’t so interesting to them. Alternatively try keeping the soil damp. Cats prefer dry soil.
